Product Information

Whatever type of tobacco pipe reamer you choose, make sure that you use it regularly to keep your smoking experience enjoyable. How to use a pipe reamer? The most commonly used woods for tobacco pipes are briar, cherry, and maple. These are all hardwoods with a relatively low moisture content, which makes them good for smoking. Cigarettes are typically less expensive than pipe tobacco, but pipes offer a more flavorful smoking experience. Pipe smokers also don’t have to worry about the health risks associated with cigarettes, such as secondhand smoke and lung cancer. However, pipe smoking can still be harmful to your health if you’re not careful. The main difference between both categories is that hard materials are usually unaffected by the heat produced by the machining process and may actually benefit from it. The down side is that they are usually very brittle, requiring slightly blunt cutting edges to avoid fracture. This increases the forces involved in machining and for this reason hard materials are usually not recommended for light machinery. Heat treated materials, on the other side, are usually much tougher and have no problem holding a sharp edge without chipping under less favourable conditions (like under vibration). This makes them adequate for hand tools and light machines. [6] Common tool materials

A tobacco pipe reamer is a tool used to clean the inside of a tobacco pipe. They come in a variety of shapes and sizes, but all do the same job: remove the built-up resin from the bowl and stem of your pipe. Another use of reamed holes is to receive a specialized bolt that has an unthreaded shoulder - also called a shoulder bolt. This type of bolt is commonly used to replace hot peened rivets during the seismic retrofit of structures. After applying it to the old bowl, you should verify that it turned out to be almost brand fresh without the “fresh pipe” flavor. It can also fit into the shortest 0.75-inch bowl pipes.

There are three main types of pipe reamers: the tapered, plug and knife. The tapered reamer is the most common type and has a gradual taper from the point to the handle. It’s best for cleaning pipes with a small diameter bore. Shell reamers are designed for reaming bearing and other similar items. They are fluted almost their whole length. Bristle brushes are also popular among pipe smokers because they can remove debris without damaging the bowl or tubing. They come in a variety of shapes and sizes, so it’s important to find the one that is best suited for your smoking device. A pipe reamer is a tool used to clean the inside of a pipe. It can also be used to enlarge the diameter of a pipe. There are many different types of pipe reamers available on the market, so it’s important to know which one is right for you. The geometry of a hole drilled in metal by a twist drill may not be accurate enough (close enough to a true cylinder of a certain precise diameter) and may not have the required smooth surface finish for certain engineering applications. Although modern twist drills can perform excellently in many cases—usually producing sufficiently accurate holes for most applications—sometimes the stringency of the requirements for the hole's geometry and finish necessitate two operations: a drilling to slightly undersize, followed by reaming with a reamer. The planned difference between the drill diameter and the reamer diameter is called an allowance. (It allows for the removal of a certain small amount of material.) The allowance should be < 0.2mm (.008 in) for soft materials and < 0.13mm (.005 in) for hard materials. Larger allowances can damage the reamer. The drilled hole should not be enlarged by more than 5% of the drilled diameter. Drilling followed by reaming generally produces hole geometry and finish that is as close to theoretical perfection as possible. (The other methods of hole creation that approach nearest to perfection under certain conditions are boring [especially single-point boring] and internal cylindrical grinding.)

During the process of reaming friction causes the part and the tool to heat up. Proper lubrication cools the tool, which increases the life of the tool. Another benefit of lubrication includes higher cutting speeds. This decreases production times. Lubrication also removes chips and contributes to a better workpiece finish. Mineral oils, synthetic oils, and water-soluble oils are used for lubrication and applied by flooding or spraying. In the case of some materials only cold air is needed to cool the workpiece. This is applied by air jet [6] or vortex tube. [7] Work Material Like other cutting tools, there are two categories of materials used to build reamers: heat treated and hard. Heat treated materials are composed by different steels, most notably plain carbon (unalloyed, considered obsolete today) and high-speed steels. The most common hard material is tungsten carbide (solid or tipped), but reamers with edges of cubic boron nitride (CBN) or diamond also exist. [6]

The final hole size that is achieved by a reamer subsequently depends on the reaming process being used in conjunction with the reamer design and materials involved. Studies have been conducted which demonstrate the effect of coolant use during reaming. [4] The continuous use of a coolant stream during the reaming process has been shown to consistently (75% of the time) result in hole sizes that are 0.0001 in. (0.0025mm) larger than the reamer itself, with a process spread of +/- 0.0002 in. the remainder of the time. Similarly, using a semi-wet reaming process often results in hole sizes that are 0.0004 in. larger than the reamer itself, approximately 60% of the time, with a process spread of 0.0006 in. favoring an increase in size. Dry reaming should be discouraged due to its low level of repeatability (20%) in size and wide process spread of sizes up to 0.0012 in. (0.030mm) larger than the reamer size. A typical reamer consists of a set of parallel straight or helical cutting edges along the length of a cylindrical body. Each cutting edge is ground at a slight angle and with a slight undercut below the cutting edge. Reamers must combine both hardness in the cutting edges, for long life, and toughness, so that the tool does not fail under the normal forces of use. They should only be used to remove small amounts of material. This ensures a long life for the reamer and a superior finish to the hole. To use a pipe reamer, you first need to determine the size of the reamer. The diameter of the reamer should be slightly smaller than the pipe you are trying to clean. Next, lubricate the reamer with a pipe cleaner or some other type of lubricant.

The Senior Pipe Reamer . With tapered sharp edges and a V-shaped bottom (which clearly goes great for V-shaped chambers), this reamer tool is suitable for most tubing. This reamer is liked because the diameter of the reamer shifts with a little torque. This ensures that when you ream, you will steadily expand the reamer to accommodate the cake, making it the best reamer to be used on your pipes. Combination reamer [ edit ] This combination reamer was made for a long run, tight tolerance electronic parts. You will need a tamper, scraper, knife, and reamer, these are the basic pipe smoking accessories. Pipe tools come in many different shapes, sizes, and finishes with different prodders, pokers, scrapers, and cutters.An adjustable hand reamer can cover a small range of sizes. They are generally referenced by a letter which equates to a size range. The disposable blades slide along a tapered groove. The act of tightening and loosening the restraining nuts at each end varies the size that may be cut. The absence of any spiral in the flutes restricts them to light usage (minimal material removal per setting) as they have a tendency to chatter. They are also restricted to usage in unbroken holes. If a hole has an axial split along it, such as a split bush or a clamping hole, each straight tooth will in turn drop into the gap causing the other teeth to retract from their cutting position. This also gives rise to chatter marks and defeats the purpose of using the reamer to size a hole. The plug reamer has a cylindrical shape and is best for pipes with a large diameter bore. It should be used when there is significant cake in the bowl. The knife reamer is tapered and sharp on one side, like a blade. It’s best for removing deposits from deeper down in the pipe when it cannot be reached with other tools such as brushes or cleaners. Is smoking tobacco from a pipe better than cigarettes? A straight reamer has a sharp point to it. This makes the pipe cleaner very effective at removing tars and other debris from your smoking device, but care should be taken as they can also damage your bowl. It’s best if you use this type of tobacco pipe reamers on non-ferrous metal bowls because stainless steel ones are prone to scratching. A straight reamer is used to make only a minor enlargement to a hole. The entry end of the reamer will have a slight taper, the length of which will depend on its type. This produces a self centering action as it enters the raw hole. The larger proportion of the length will be of a constant diameter.
